[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 ZsK'</7

配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： HjF'~n  
enableservice('AutomationServer', true) 5A=xFj{  
enableservice('AutomationServer') #<V
'gE  
ewff(e9  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 O6/=/-?N=c  
/7HIL?r  
在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： H&K)q5~  
1. 在FRED脚本编辑界面找到参考. 6V_5BpXt  
2. 找到Matlab Automation Server Type Library Z(`K6`KM  
3. 将名字改为MLAPP w!Lb;4x ?  
B(vz$QE,$r  
[`nyq)  
在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 O7_NXfh|

现在将脚本代码公布如下，此脚本执行如下几个步骤： cngPc]?N  
1. 创建Matlab服务器。 tp3N5I  
2. 移动探测面对于前一聚焦面的位置。 eMMiSO!3  
3. 在探测面追迹光线 fHp#Gi3Lz  
4. 在探测面计算照度 u6&Ixi/s'  
5. 使用PutWorkspaceData发送照度数据到Matlab ,3TD $2};.  
6. 使用PutFullMatrix发送标量场数据到Matlab中 *xNjhR]7v  
7. 用Matlab画出照度数据 :r+ 1>F$o  
8. 在Matlab计算照度平均值 WQ
`P^5e  
9. 返回数据到FRED中 e/I{N0SR
